Humans are too spread over the earth and have things too good (food, water, shelter) for evolution to take place.

Now, if you took like 50 humans and put them on a different planet and didn't mingle with them again, in a million years they would probably be very different than earthbound humans.

Eventually yeah. But it will take millions of years. Also, for evolution to take place, it's an advantage if two groups individuals are separated from each other a longer period. The length of this period depends very much on the life cycle length and reproductive rate of the species.
So humans will evolve much more slowly than other species. Some species (Typically insects or plants) can actually evolve within the lifetime of one or two human beings.

i imagine what you're offering is almost an inner "founder outcome", the position some examples of a sparkling species get up interior of a inhabitants, and could hotel to incest to produce an entire new inhabitants. the region is that this is not how evolution works. there is in no way been an get mutually of two persons growing a sparkling species interior of a inhabitants, or perhaps an entire inhabitants purely growing a sparkling species. The transition is sluggish - to the point the position you in ordinary words observe the speciation in case you're taking a step back and seem at the inhabitants to a) a "sister" inhabitants that has been separated from it for most generations, or b) examples of the inhabitants from many generations back. As for the unique inhabitants that each little thing got here from, it probably arose earlier to the evolution of sexual reproduction - formerly incest would were an situation. The transition from asexual to sexual would have also been a steady one - first concerning hermaphrodites (permitting genetic replace, yet not requiring it), then finally ensuing in extremely good men and women. the easy truth, even with the undeniable fact that, is that inbreeding does ensue in nature. Over a era or 2 (even in people), this is not a large deal, biologically talking - this is purely that we people have the psychological skill to appreciate the concept of kinfolk timber, and characteristic placed a societal taboo in position. Lab rats, as an get mutually, were inbred for 1000's of generations, to the point the position they're genetically same. Purebred animals of any species were further inbred. They do have issues, yet they're nevertheless biologically doable. this is actual that severe inbreeding can decrease variety, and thereby decrease a species health - yet bear in mind that evolution would not artwork in a black/white stay/die trend. this is all opportunities. An undeserving inhabitants would have a extra sturdy time, would have a decrease danger of survival, even with the undeniable fact that this is not a lack of existence sentence. even as tremendous scale inbreeding could be an evolutionary setback, it may also bolster numbers to the point the position generic interbreeding and organic version can get them back heading in the right direction.

I think that the only major selective pressure is sexual selection. The criteria for being positively selected are intelligence and beauty. If you are intelligent and or beautiful you will have more chance of reproduction than if you were stupid/ugly.

Therefore, I propose that humans will become more attractive and clever.

As for evolving into a different species: speciation is aided by isolation and mutation. In the society we live in today, in which people move all over the world, I doubt that the arrival of a completely new "species" will occur (it would require at least 2 mutants who would then breed together, and then a lot of inbreeding after that: maybe in Alabama)

All that can be said is, that possibility exists. Though it might take a long time.
But 'will humans evolve' is a question which cant be answered with certainty. There have been many species which have become extinct without evolving. Mainly because they were helpless to cope changes in their surroundings. But unlike them, i have a feeling that we will be the first specie on this planet who might committ sucide.

Evolution is constant. We as a species are evolving right now. It happens so slowly that we won't actually become anatomically different for millions of years. So for us to become an entirely different species will take eons. But it will happen eventually provided our species survives the next catastophe--whatever it may be.

Evolution occurs to weed out the weak designs and let the strong prosper. However, humans, no matter how weak, do not depend on their bodies as much as other creatures. Humans like other apes have tools to make life easier for themselves. Tools have allowed us to evolve into what we are today, however, they may hinder us from evolving to some extreme state. If you look at human design, it's kind of weak. We have no outer protection in the form of tough skin or shell. We have no claws and our teeth are practically useless in fending off predators. We can't run super fast and aren't very strong. Without our tools, we may not have gone very far. Now instead of us evolving, it is our tools doing the evolving for us. Unless our environment takes a drastic turn, we may not evolve very much at all.

yes.in due course the humans may evolve into some othe species having shorter legs and a very big head as the mental exercises are taking placeof the physical ones.

Evolution consists of mutations that make the species better able to survive. There are those that are born smarter or stronger and therefore better able to survive, however in our culture the best looking and smoothest talking person is the one who has the most children. So I ask you what are we evolving into?

Where are all the between creatures evolving from one species to the next, including human. Wouldn't humans still be evolving?

Of course we won't evolve into some other species.
